plants be natives of high and bleak localities, where 

 they enjoy the purest atmosphere, and though, in 

 their native habitats, they endure a great degree of 

 cold, still, when introduced into our gardens, and 

 planted upon a Rockery, many of them will neither 

 stand the winter frosts, nor yet bear the strong and 

 sharp gusts of wind. The former, alternating with 

 mild weather, keep a degree of vitality in their system, 

 which they do not experience in their Alpine abodes, 

 and thus they are more exposed to injuries from the 

 latter.
